BRAUN, or SYRACUSE, NEW YORK, ASSIGNOR r TH-E' #BROSPERITY 00M- PANY ING, or SYRACUSE, NEW YORK, A CORPORATION OF NEW YORK DRYING ATTACHMENT FOR vPRESSING' MACHINES Application filedgJanuary' 20, 1928. Serial No. 248,254.

This invention relates to pressing machines and has for its object a particularly simple and efficient means whereby the moisture can be removed from thebartic'le being pressed and the padding on one o'f the pressing elements in a comparatively short time, :and'also whereby the vapor generated in the garment or article from the moisture therein by thehead of the pressing elements, is free to ventilate or pass off durin 'the r'essin 1 b b operation and-as it-is generated.

The invention consists inthe novel features and in the combinations and constructions hereinafter set forth and claimed.

'In describing this invention, reference is had to 'theaccompanying drawings in which like characters designate corresponding parts in all the views.

Figure 1 is a side elevation of a pressing nachine embodying my invention.

Figure 5is an enlarged fragmentary sectional view of the ventilating and presser plate.

' In pressing cloths and garments, particularly nap goods which contain moisture or which are moistened elther 'by dampening" cloth or bysteam projected thereinto during the pressing operation, the steam or'moisture is trapped in the garment .untilthe pressis opened, and furthermore the vapor or steam :condenses in the garment when the press is opened so that the air must be passed through the: garment for a much longertime to remove the condensation. In fact it is not ,possible to remove all the condensation by passing air through the garment, particularly if the current of air is created by, suction or theou-terair drawn through thegarment. 1 i

- V The invention comprises a ventilating and movable pressing element or head and, overlying the pressing face thereof, means for blowing air through the stationary pressing element or buck, the article thereon and'the Ventilating and presser platen element, the press being so formed that the air or vapor can ventilate comparatively easy therethrough and pass out throughthe edges of'the platen element when the press is-closed, and

presser' platen element associated with the directly through the platen element when the press is open and the plate held onto the Work. v

The pressing machine may be of any suitable form, size or construction. That here shown includes a head 1 movable toward and from the buck 2, carried by a suitable bracket .3 which is mounted upon a bench or table 4,

known, further description of this feature is or through the garment is very old'and well 1 though to be unnecessary, particularly as it a I forms no part of this invention, except that some sort of molstening means for moistening the article being pressed is provided in tailor machines or machines for pressingnap goods or knit goods. I

The head 1 is actuated in any suitable manner and is here shown as carried by a yoke lever 6 pivoted/at 7 between its'ends, this lever being here shown as factuated'by a pedal lever 8 pivoted at 9 to tlie fr'ameand having an upwardly extending arm 10 pivotedat 11 to a link lQv'hic'h is pivoted at-13 to'the rear arm of the lever 6 the pedal 8 having a plate 14 at the frontend; V The parts '10 and 12 constitute a toggle.

Obviously, when the pedal8 is depressed, the

toggle will be straightened and the press closed.

The press is here shown as held closed by the latching mechanism designated generally 15, which is tripped by a kick ofi' lever 16. The press is opened by a counterweight 17 and spring 18. The opening and closing movement of the toggle is limited by stops 19 and 20 coacting with a stop 10 on the lever arm 10.

The features thus far specifically described are old and well known in the art and forms no part of this invention.

21 designates the ventilating and presser platen element forming the subject matter of the invention, this being associated with the head 1 and normally overlying the pressing face thereof. It is so formed as to have communicating passages extending lengthwise and crosswise therethrough, and also through its upper and lower faces, these communicating passages permitting the free escape of vapor and air when the press head is closed, and particularly the escape of vapor as it is generated by the heat from head 1 from the moisture in the garment or for permitting the escape of vapor or steam when it is projected from the head onto the garment when the head is closed or projected through the garment from the lower buck when the head is closed.

The presser platen element 21 is here shown as made up of a plurality of layers 22 of reticulated material or wire mesh, the upper and lower layers being continuous and passing around a rod or wire 23 which forms a frame for the platen element, which frame fits around the edge of the head 1 and provides a marginal flange 2e around the edge of the head 1, or in other words, a seat or depression for receiving head 1.

25 designates a carrier for he ventilating and presser platen element, this carrier being in the form of a yoke lever which is preferably pivoted coaxially with the yoke lever 6.

The platen element 21 is held against the head 1 and caused to follow the head 1, when unrestrained, by 1 cans here shown as a spring 2(3 connected at one end the frame, and its other end to a rearwardly eXtendin arm 27 on the supporting lever Means is provided for automatically holding the presser platen element onto the work on the buck 1 during the opening of the press, such means being manually releasable. The holding means here shown comprises two members coacting with a ratcheting action, one member being a segment 28 pivoted at 29 to the frame and having ratchet teeth 30 and the other member being a pawl 31 coacting with the ratchet teeth.

The member 28 is actuated by the support 25 and is connected thereto by a link 32 pivoted at to the arm 27 and at 3% to a rock arm 35 associated with segment 28. The pawl 31 is pivoted at 31 to the frame and has a rock arm 31 which is manually operable. This means as illustrated is a link 31 extending to the front of the machine where it is provided with a handle 37.

A spring 38 acts on the link 36 or the pawl 31 to urge the pawl toward the ratchet teeth. Obviously, during the closing movement of the head, the ratchet teeth 30 will ratchet along the pawl 31 and when the head is closed, the pawl will hold the segment 28, and hence the platen element 21 from upward movement with the head 6 and upon the forward pulling the handle 37, the pawl will be operated to release the segment 28 permitting the spring 26 to move the platen element 21 upwardly against the head.

The lower buck 2 is usually provided with a padding and with means for blowing a drying fluid as air through the padding 39, the article thereon and the ventilating and presser element 21.

40 is a pipe for air, this pipe extending upwardly through the bracket 3 to a distributing channel 41 in the buck, which channel is provided with suitable outlet perforations eX- ten ding lengthwise of the buck and under the padding 39. The flow of air through the pipe 40 from an intake pipe 42 is controlled by a suitable valve located in a casing 43 and operated by a push button 44. Any suitable valve may be used.

In operation, the press is closed on the work on the buck 2 and the moisture or vapor generated in the garment by the heat from the head 1 or the vapor projected into the garment, easily escapes without being trapped in the garment, through the ventilating presser platen element. When the press is opened by operating the kick off pedal 16, the ventilating platen element remains on the garment and upon the depression of the button is, air will be blown through the garment quickly removing the vapor and moisture therein.

The platen element 21 is provided with a suitable handle 45 by means of which it may be pulled down onto the garment at any time without actuating the head.

I am aware that it is well known to dry the garment or article, and the padding in laundry and garment pressing machines, but believe am first to provide a ventilating and presser platen element through which the moisture and vapor is always free to pass olf comparatively unrestrained, and also, the first to provide means for blowing air, when the press is open, directly through the padding and the article thereon without disarranging the garment.

By my invention, a garment can be pressed and dried with considerable time saving, because in machines heretofore used the moisture became trapped in the garment when the buck, the work thereon and the ventilat- 'a head movabl'etoward and-from the buck,.an open work ventilatingand-presser elementas- M 'sociated with the 'head' and separable:there- 1.
